Bug with Skitterbots not counting as allies.

"

I am playing a Guardian Aurabot with a Miner friend. I took the ascendancy Radiant Crusade so we get onslaught while having 5 allies.

My allies should be;

-My miner friend.
-His golem.
-My golem.
-My holy relic
-His skitterbots.

But we are not getting the onslaught buff. If we instead repeat those allies but he doesnt summon skitterbots and I summon a zombie. We DO get the onslaught buff. So it seems that skitterbots, while having a minion tag do not count towards the ally count. The wiki says this;

'''Ally refers to any creature on the player's side. They are subject to effects granted by equipment and skills, which have in their description "grants (effect) to you and your allies". Allies include:

players in your party
minions (includes minions of party members) 1
totems (includes totems of party members) 1'''

So I guess its a bug?
